Min. cutting height
The minimum cutting height provided by the lawnmower — that is, the smallest height of grass that can remain after the passage of the machine. It makes sense to pay attention to this indicator mainly in cases where the lawn is planned to be cut as short as possible. In addition, the lower the minimum height (with the same maximum), the wider the height adjustment range of this model.
Number of height settings
The number of cutting height settings provided by the lawn mower. The more such settings (with the same adjustment range) — the more accurately you can choose the mowing height. Note that in some robots (see "Type") this number reaches 30 or more with a range of 30 to 60 mm; in other words, you can select the height to the nearest millimetre.
Mulching
Possibility of work of a lawn-mower in the mode of a mulching.
Mulching is the chopping and automatic spreading of mowed grass over the site. This is one of the most convenient and at the same time practical methods of vegetation disposal. So, it does not need to be collected, and the resulting coating (mulch) performs a number of useful functions: it fertilizes the soil, reduces its heating and evaporation of moisture in hot weather, and also keeps the top layer loose.
Note that some lawn mowers allow you to use a nozzle purchased separately for mulching. However, such models are not included in this category: mulching in our catalog is indicated only for models that support this function out of the box.
Grass ejection
Direction of ejection of grass cut by the lawnmower.
The main options for the direction of ejection are back or sideways; there are also models in which you can choose the direction. At the same time, we note that in classic units, the ejection back is almost always carried out
into the bag(up to the point that when the bag is removed, the hole is automatically covered with a lid), but when the bag is ejected from the
side, it may not be — this is convenient, for example, when mulching ( see above).
Also note that riders (see "Type") have their own specifics: in units with rear discharge, after removing the bag, it is necessary to install a special plug, and then the cut grass will simply remain under the deck. In some
mini-tractors, a similar way of working (without a bag) is provided initially; it is also considered a rear ejection, although the grass does not flow backwards, but downwards.
Deck material
The material from which the deck is made is a protective casing that covers the cutting tool of a lawn mower or trimmer. In modern mowers there are such options:
— Plastic. The cheapest and at the same time the least durable material.
— Aluminium alloy. The most advanced option: these decks are durable, lightweight and less prone to corrosion, but quite expensive.
— Steel. It has greater strength than aluminium alloy and costs less, but is heavier and more prone to corrosion.
